A process for generating at least one liquid oxygen product (LOX) and a gaseous oxygen product (GOX) by low-temperature separation of air (AIR) in a distillation column system (S) of an air separation facility, in which, for obtaining the liquid oxygen product (LOX), a liquid fraction having a first, relatively high oxygen content is taken off from a separation column (S2) of the distillation column system (S) and discharged in the liquid state from the air separation facility, and in which, for obtaining the gaseous oxygen product (GOX) a liquid fraction having a second, lower oxygen content is withdrawn from the same separation column (S2) of the distillation column system (S), vaporized at least in a mixed column (S3) at a mixed column pressure against mixed column air, and discharged from the air separation facility in the gaseous state. A corresponding air separation facility is likewise subject matter of the invention. |
